HYDROCARBON-BURNING APPARATUS.

" SPECIFICATION forming part of Letters Patent No. 752,195, dated February 16, 1904.

i Application iiled May 29, 1902.

Be it known th at I, WILLIAM NEWTON BEST, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Hydrocarbon-Burning Apparatus, of which the following is a specification.

An object of this invention is to provide a superior apparatus for burning liquid hydro-I carbon in locomotive and stationary furnaces and lire-boxes and in other places in which' hydrocarbons are to be consumed.

One object of the invention is to provide means whereby the operation of the apparatus may be perfectly controlled with the greatest ease and convenience possible and whereby the apparatus may be operated from the deck of a locomotive or from any other position where the fireman or engineer may be stationed.

Another object is to provide for producing a uniform lire, filling the surface of the rebox regardless of any canting of the engine or locomotive which may bring the nozzle of the burner out of a horizontal position.

Another object ofthe invention is to provide means whereby the fire may be reduced l very low and yet will be retained with a wide flame which will cover the area of the furnace.

An object of the invention is to produce a A. superior flat fan-shape blaze and at thesame time to so atomize the oil that perfect combustion is attainable.

Heretofore a diiiiculty to be overcome has been that when an oil-burning locomotive hasl been brought to a standstill, thereby necessitating the lowering of the ireto a minimum, the oil will run out or drip from the burner while the steam and oil are reduced to the minimum and will form in a pool on the bottom of the lire-box. By the present invention this difculty is avoided and the iire may be turned down to any required extent and no dripping or running over of the oil vwill ensue. Another object is to provide more nearly invention.

lated and the removal of which is required.

Another object is that if the oilway becomes clogged by foreign substances, such as waste y or residuum in the oil, the same can be removed by steam applied through the oil-pipe by'diverting thereto steam which would otherwise be applied to the atom'izer of the burner. Valved connections for suchoperation are so arranged that the clearing of the atomizer may be accomplished while the locomotive isV in motion as well as while standing still and with stationary and marine boilers as well as with locomotives.

Another object of this invention is to'pro- Y vide means by which a combustible liquid can be sobroken up and atomized by a force of steam or air that perfect combustion is obtainable, and by the peculiar formation of the mouth of the burner the oil after being struck by the steam or air Will be carried to produce a fan-shaped blaze that may ll the furnace throughout its full width, keeping all points of the furnace up to the igniting temperature. So perfectly does this burner work that the igniting-point is Within a few inches of the nose of the burner. I

The accompanying drawings illustrate the Figure I is a fragmental view, partly in section, illustrating the invention as adapted for a locomotive. The atomizer is viewed from the rear. Fig. II is an elevation from the right of Fig. I, showing the atomizer and a 4portion of the lever for controlling the same. Fig. III is a plan of the atomizer shown in Fig. II. Fig.xIV is a fragmental section on irregular line IV IV, Fig. III. Fig. V is a front elevation of the atomizer shown in Figs. I, II, III, and IV. Fig. VI is a view of the front end of the atomizer, the movable nozzlepiece being removed to expose the end of the tablet. Fig. VII is an elevation of another form of the steam and oil connections .and atomizer which form a part of this invention. This is a desirable form for marine and stationary boilers. Fig. VIII is a fragmental plan of the atomizer shown in Fig. VII, the connections being broken away to contract the view. Fig. IX is a front elevation of the atomizer shown in Figs. VII and VIII. Fig. X is a detail view of the brace for the adjusting device of the nozzle-piece shown in Fig. VII. Figs. XLXII, and XIII are details of the oil-regulating valve.

Referring to the forms shown in Figs. I to VI, inclusive, 1 designates the atomizer; 2 and 3, the pipes, respectively, for supplying liquid fuel and an expansive fluid thereto; 4, a regulating and cut-off valve for the oil-pipe; 5, a valve-stem for valve 4, and 6 a lever for operating said valve-stem; 7, a graduated quadrant for said lever by which the operator can determine to a nicety the amount of oil admitted to the atomizer. In practical use on a locomotive the lever 6 and quadrant 7 will be located in the cab within reach of the fireman or engineer, as the case may be. 8 is a tensionspring to frictionally maintain the lever in any determined position. 9 is a temporary stop for thelever 6 to stop the lever in position to allow a minimum quantity of oil to be fed to the atomizer. This stop may be a spring-catch or a hinged attachment which will allow the lever 6 to be moved into position for entirely cutting off the oil. 10 designates a screw-clamp for clamping the quadrant-lever in closed position, so that it may not be accidentally opened when the fire is shut down. 11 is a valved connection between the steam-pipe 3 and the oilpipe 2, and 12 is a valve in the steam-pipe 3 between the connection 11 and the atomizer 1, whereby when the valves 4 and 12 are closed and the valved connection 11 opened steam may be passed through the oil-pipe to the atomizer, thus to drive out any material which may clog the oil-passage in the atomizer. 13 and 14 are connecting-rods leading from the valves 11 and 12, respectively, to the cab (not shown) for the purpose of opening' and closing said valves. 15 is a steam-chamber aroundthe oilpipe 2 between the source of supply(not shown) A and the regulating-valve 4. The atomizer has an outlet 16 opening up through a tablet 17, which forms one wall of a steam-chamber 18 and extends forward beyond the other wall 19 of said chamber. 2O is a vertical way perpendicular to the tablet 17, formed in the wall 19, and is formed slightly tapering by means of inclined walls 27. The way extends clear across the wall 19. A movable nozzle-piece 21 is mounted on the way 2O to move toward and from the tablet 17. The under face 22 of the nozzle-piece or lip 21 is inclined converging vforwardly toward the tablet and terminating near but rearward of the outlet 16. The tablet is recessed at 23, and the recess leads forwardly from the outlet 16 to the front end of the atomizer. 24 designates guards at the opposite sides of the outlet 16 and the extension 23 thereof formed by the recess in the tablet. Said recess has flaring side walls formed by the guards 24, which have oblique diverging walls 25, as shown in Fig. III, so that the substances in passing from the outlet 16 and from thenozzle over the recess 23 may flare or spread laterally. The guards 24 prevent the pressure of the expansive fluid from discharging any liquid fuel prematurely from theside s of the nozzle, and thus cause the fuel to be taken up, atomized, and driven forwardly in the desired fan shape into the firespace where combustion is to take place. The guards prevent any dripping of the liquid over the sides of the nozzle and compels the fuel to take the requisite course. 26 designates the outlet-opening of the nozzle between the nozzle-piece or lip 21 and the face of the tablet. Said steam or air outlet 26 is wider at its edges than at the middle, so that a greater quantity of the expansive fluid will be emitted at the edges of the outlet than at the middle thereof, thereby supplying greater force at the edges for taking up and propelling the liquid fuel from the outlet.

In order to produce the perfect breaking up, atomizing, and spreading of the liquid fuel hereinbefore referred to, it is necessary to reduce that portion of the tablet over which the stem and oil pass approximately three sixtyfourths of an inch below that portion of the tablet over which the steam alone passes, the reduced portion or recess 23, which forms the final oil-outlet, being directly in front of the oil opening` or outlet 16, through which the oil is emitted to the air or steam blast. The recess 23 gradually flares, increasing in width forwardly, leaving the sides and surface of the steam-tablet of the atomizer practically in one plane. Then by making the steam or air slot larger atv each side than at the middle I am able to carry the steam or air combined with the atomized liquid fuel to produce the width of flame necessary to span the width of the furnace. It is to be understood that when the width of a fire-box or furnace is but three feet the atomizer-slot should not be so large in cross-sectional area at its edges as when the atomizer is for the furnaceof a large boiler, which may be, say, eight feet in width. The slot of the nozzle must be appropriately enlarged on each side of the burner-lip forincreasing the flow of oil at the edges of the blaze, so that fuel will be supplied for the increasing blaze as it widens.

The peculiar construction of the atomizerlip and the means by which it can be raisedv is such that the sand now commonly used on oil-burning locomotives for cleaning the llues from soot cannot collect upon the burner and IOO IIO

eign substance,l because theV taper .at 27 is sogive trouble when the atomizer-lip is raised to clear the atomizer-.channel from any forslight that it is impossibleV for sand tocollect in the ways 20, and the construction is such that the force of steam or air can be used to clean the ways from dust, sand, or other foreign substance when the atomizer-lip is being lowered to its fixed position. The atomizer may be cleaned when the locomotive is in motion or at a standstill, at the will of the operator.

Should any foreign obstructionsuch as sand, particles of waste, or other solid matter--collect in the oilway d of the burner, the same can be removed by closing the oil-regulating valve 4, then shutting the valve 12, and then opening blow-out valve 11, which may be done at the will of the operator in the cab.

28 is a lug on the atomizer-,for the purpose of carrying the burner in a fixed position and also to easily adjust the pitch of the burner by the use of liners, (not shown,) which can be placed between this lug and the rear sheet of boiler (not shown) when the lug does not slant sufficiently to give the desired pitch." By the use of this lug attachment the atomizer is held to the boiler at any desired pitch and may be removed without removing the apron of the ash-pan as is required by other burners.

In the locomotive-burner means A are provided for raising and lowering the atomizerlip` by means of a lever 29 in the cab. 'It is to be understood that, if desired, the lip'may be operated by a set-screw and nuts 30, 31, and 32, as shown in Fig. VII.

I provide superior means for operating and adjusting the atomizer-lip by two wedge members 33, each being independent of the other and adjustably mounted on a cross-bar 34 by means of nuts 35. The wedge' members 33 play in ways 36 in arms 37 ofthe nozzle-piece 21, which extend on the opposite sides of the body 1 of the atomizer and are held down by shoulders 38 39 on the -body 1. rlhe wedge members 33 are to be simultaneously moved to and fro by means of the bar 34, and said bar may be operated by any suitable connection. 40 designates such a connection adjust- Lably connected with the bar 34 by set-nuts l41 and 42 and 'operated by the lever- 2-9, which may extend up into the cab. By this wedge device, comprising the two independent rods 33, acting on the opposite sides of the nozzlepiece 21, each side ofthe nozzle-piece will be drawn down independently o`f the other side, thereby allowing the nozzle-piece to be forced into and perfectly held in its closed position.

The set-nuts 35 enable the attendant to adjust the wedge device so that` the bar 34 will act equally upon both of the members 33 whileat right angles thereto, so that approximately the same strain is applied on eachiside of the nozzle-piece to bring it into and hold it in -closed position` tive and other fire boxes on which this apparat-us lmay be applied, I do not limit myself to adjusting Vthe'device by means of a lever 279. Another `method of adjustment is shown in Fig. VII, in which the set-nuts 31 and 32 are employed, acting on the brace 43, which may be fastened to the atomizer-pipes 2 and 3.

The atomizer-body is desirably furnished with bosses 44 and 45, integral with said body, the v same being respectively provided with screw-threaded perforations 46 47, communicating with the passages a 18 forthe combustibles, such as liquid fuel and air, which are to be passed through the respective passages of the atomizer. By this arrangement the pipes 2 3 maybe connected to the'atornizerbody with great ease and convenience, and by means of this construction I avoid the necessity whioh often occurs of cutting away the deck'- castings of locomotives as `now constructed.' i

One or both walls ofthe nozzle-way 20 may project up above the gate or nozzle-piece 21 when the same is in closed position, so that said nozzle-piece will not have to be raised above the top of said way in order to fully open the nozzle. This projecting wall serves as a guard to prevent any accidental placing of the atomizer in such a position that xed external objects might interfere with the working of the nozzle-piece 21. The inclined face 48 of the wedge device 33 is intended to act on the wall of the way 36 to start the nozzlepiece away from the tablet 17 when the members 33 are pushed forward. The members 33 are to have suliicient endwise play to allow IOO the nozzle-piece 2l to' be sufliciently opened for cleansing the atomizer. vThe connection 40 may be arranged to engage the body 1 to prevent the members 33 from moving too far forward.

When itis 'desired to cleanse the air or steam passage of the atomizer from any accumulations external to or inside the air or steam passage 18, the members 33 will be moved forward, thereby bringing the oblique face 48 against the upper wall I) of the way 36, there'- by starting the nozzle-piece away from the tablet 17, whereupon the force of the expansible Huid within the air or steam passage 18,

actingupon the oblique face 22 of the nozzle- IIO piece, will lift the same, at the same time removing fromthe passage and from around the outlet thereof any accumulations or foreign substances which may accumulatein the operation of the burner. Owing to the tapering form of the way 20, the air or steam will at the same time blow through said way and keep it clear, so that the nozzle-piece or lip may be closed down again. When it is desired to cleanse the passage a, the valves 4 and 12 will be closed and valve 11 opened, or, if desired,the valves 12 and 11 may both be opened, thereby simultaneously forcing steam or air through the two passages a and 18.

ignates a drain-valve of any well-known construction to drain from the steam-pipe any Y water of condensation which may accumulate.

Said valve may be placed at any point on the line of the steam connection leading to the atomizer-nozzle.

The cut-off valve 4 for the oil-supply is preferably formed with a tapering plug 50, having anotch 51 at one side of the passage 52 through said valve, so that when nearly closed the oil may 'be so accurately adjusted that the oil may be reduced to the minimum.

The oil-heater 15 is desirably placed on the opposite side of the valve4 from the atomizer, so that the oil may be heated immediately before it is fed to the valve 4 and will be thin and Huid.

53 designates a valved steam-pipe leading into the oil-heater 15.

54 is alvalved pipe to drain away the condensation from the oil-heater 15.

55 is a shoulder on the body of the atomizer to support the wedge members 33 when the latch or nozzle-piece is being raised.

The lever 6, as shown in Fig. I, holds the valve 4 nearly closed, and when the lire is cut down to the minimum the catch, stop, or guard attachment 9 lies upon the quadrant and the lever is pressed against it. In actual operation this is very important in order to regulate theow of oil to the burner in accurate quantities. In going uphill or when the locomotive is in motion the lever is moved by the operator away from the stop or guard to open the valve 4, as required; but when the engine is stopped or is going downhill the operator moves the lever into the position shown, where it abuts against the guard.

In operation on locomotives it is diflicult for a burner to be so operated that whenever the engine is used to pull its full tonnage over a grade and then the locomotive goes downgrade for several miles the fire in the fire-box may be reduced until it becomes a very small tire, and in order to do this with low gravities of oil I have provided the superheater 15 to heat the oil easily up to about 12()O Fahrenheit approximately. Then by means of the oil-regulating valve 4, the opening of which I file, as shown at 51 invFig. XI, I can so regulate and reduce the quantity of oil that the desired small fire can be produced and regulated as required.

Adifculty heretofore on oil-burning locomotives and stationary boilers` has been the uneven' distribution of heat. That is obviated in this burner, which is so constructed that it makes a iire that will span the full width of the fire-box. As the air is taken in from below the re, any uneven distribution of the heat caused by the imperfectly-constructed burners that do not iill the require- ,ments in actual practice of the forced intermittent vdraft of a locomotive or the draft in large boilers would cause the flues and side sheets to leak. By the peculiar construction of this oil-burning apparatus I overcome these diiculties -by so atomizing the oil as it passes out of the oil-orice inv quantities regulated by the oil-regulating valve causing the blaze to span the width of the furnace, so that the air admitted from beneath must pass through flame, as the fire-box is filled with ame, causing perfect combustion, keeping all points of the {ire-box up to the igniting temperature, and again evenly distributing the heat through the flues, and as a result I overcome the difliculties of uneven expansion.

The peculiar construction of this burner allows the pipes to be assembled in a very small space, and in the locomotive-burner this is often very desirable in order to escape deckcastings and at the same time reduce the number of pipe-fittings and reduce the rigid strain on pipe.

The valve connection 1l may be applied between the atomizer and the valve 4 of one of the supply-pipes and connected with the other supply pipe on the side of the valve 12 opposite the atomizer, as shown in Fig. I. In Fig. VII the valves 111, 112, and 114 may be manipulated in substantially the way set forth for valves 11, 12, and4 for cleaning the atomizer.

The lip c of the nozzle-piece 21 may be straight across, as shown in Fig. III, or semicircular, as shown in Fig. VIII, and the oiloutlet 16 may be formed to correspond with the form of said lip.

rlhe nozzle-piece lip c desirably terminates on a line approximately three-sixteenths of an inch rearward of the opening 16 in the tablet through which the .oil issues, so that the issuing steam or air is directed across the outlet 16 and not down into it.

I may employ various forms of construction in carrying out my invention and do not limit my invention to the exact form shown.
